I’ve always been fascinated by growing mushrooms and have tried many times with very limited success. I’m trying again with an Oyster Kit and got my first flush. However I am again battling a surface mold. This is the problem I’ve repeatedly had in past efforts. My family loves mushrooms and we would eat several pounds a week if we could so one of my goals is to build something in my basement to produce them. But I still haven’t figured out the contamination issue. From what I’ve been heard and read something the size of a closet could produce enough for a family, but I haven’t been able to find a source of concrete information of someone doing it.
